AT45DB321D-MU Description

Short technical summary and product information.

The Atmel AT45DB321D-MU is a 32Mb serial interface Flash Memory from Microchip Technology, ideal for digital voice, image, program code, and data storage. It features the Atmel RapidS serial interface, compatible with SPI for frequencies up to 66MHz.

 

The memory is organized into 8,192 pages, each with either 512 or 528 bytes. It includes two SRAM data buffers of the same size, allowing data reception during reprogramming operations. The device supports flexible erase options including page, block, sector, and chip erase.

 

Key electrical characteristics include a typical active read current of 7mA, a standby current of 25µA, and a deep power-down current of 15µA. It offers hardware and software data protection features, a 128-byte security register, and a 64-byte user programmable space. The device is rated for an industrial temperature range of -40°C to 85°C.

 

Packaged in an 8-VDFN exposed pad, the AT45DB321D-MU is designed for surface mounting. It boasts 100,000 program/erase cycles per page and a data retention of 20 years. The device is also RoHS compliant and available in green packaging options.
